Using the IPv4 Code Option

Introduction

>>>> Metanet or Meta-Net ??? <<<<<

XXXXX

• Why is this important?

The SPP Fastpath

XXXXX

• Meta-Router packets
• Meta-interface
• UDP tunnel
• Queues
• Code option

The IPv4 Meta-Net

XXXXX

• Packet path
• Filters
• Stats

Utilities and Daemons

XXXXX

• scfg
  • generic
  • information, reservation management, queue management, resource allocation/freeing
• ip_fpc
  • IPv4 filter management
• ip_fpd
  • create IPv4 fastpath
  • process LD and EX traffic
• sliced
  • process monitoring requests

Example 1

• overview of Ex1
• 1 SPP
• real-net, meta-net relations
• only ping traffic (local and remote)

Preparation

XXXXX getting files, etc

Setup the SPP

XXXXX setup script setupFP1.sh

• MIs
  • Implicit MI 0 for LD and EX
  • 1 for each FP EP plus MI 0 (LD, EX)
• Filters
  • direct incoming packet to queue
  • For LD: "--txdaddr 0 --txdport 0 --qid 0"
• Queues
  • each queue is bound to an MI
  • each MI can have 1 or more queues
  • q$N for EX and q${N-1} for LD where $N is #queues
  • pkt scheduling: weighted fair queueing

Send Traffic

Teardown the SPP

XXXXX teardown script teardownFP1.sh

Example 2

XXXXX

• simplest complete example
• all traffic
• sliced
